Turbo-Coat Acrylic Conformal Coating

Transcription

1 Product Information Turbo-Coat Acrylic Conformal Coating 2108 Introduction Techspray s new Turbo-Coat Acrylic Conformal Coating is designed to speed up board production throughput without additional investment of expensive UV systems or other capital equipment. Conformal coating cure time is often considered a production bottleneck for PCB assembly operations. Turbo-Coat dries tack-free in 3 minutes, allowing manufactures to handle boards in 1/3 the time of the leading acrylic coating! Full cure can be achieved as quickly as 10 minutes with elevated temperatures. Like all Techspray conformal coatings, Turbo-Coat can be either sprayed or brushed, or boards can be dipped directly into the coating for a thicker layer of protection. Features / Benefits Fastest Cure Dry to Touch in 3 Minutes! Faster Throughput without Capital Investment Thick Coating One-Pass Application Fast & Easy Rework & Repair IPC-CC-830 & MIL-I-46058C Tested UL94 V-0 Rated Crystal Clear & Glossy Finish UV Indicator for Black Light QC Inspection MEK, Toluene & Xylene Free Adjustable Sprayhead (Aerosol) Applications Electronic Assemblies for Automotive Aviation Consumer Electronics Appliances Industrial Meters & Control Thinning / Removal Techspray coatings can be thinned to meet production requirements using Conformal Coating Thinner (2105). Conformal Coating Remover (2510) is also available for rework and repair, although coating is often just burnt through in the soldering process for spot repairs. Thinning / Removal Techspray coatings contain Opti/Scan to allow quality control inspection of coverage and evenness of the coating on a PCB. A coated board can be passed under a standard, low-cost UV (black) light, and the coated areas glow. The brighter the glow, the thicker the coating.

2 Cure Profile Accelerated Cure: F / 65 C Ambient Cure: F / 23 C (ambient temp) Tack-Time (dry to touch): 3 74 F / 23 C (ambient temp) Cure time depends on a number of factors, including the method and thickness of application. Dilution will also change the cure profile. 149 F / 65 C is recommended as the best accelerated temperature to optimize leveling, providing the smoothest possible finish. A faster cure may be achieved, but should be thoroughly tested first.
